This application claims priority to Chinese Patent Application No. 201310256475.2, filed Jun. 25, 2013, incorporated by reference herein for all purposes.

BACKGROUND OF THE INVENTION

Certain embodiments of the present invention are directed to computer technology. More particularly, some embodiments of the invention provide systems and methods for communication technology. Merely by way of example, some embodiments of the invention have been applied to login and authorization. But it would be recognized that the invention has a much broader range of applicability.

With development of network technology, instant messaging (IM) software provides a fast, convenient and highly efficient communication platform for people so that all online users can communicate through fast and instant message exchanges via the Internet, enriching the communication manners. With development of the Internet businesses, various network operators add additional features to many third-party applications based on the instant messaging products. For instance, the users can access the Internet to search for information, publish information, and download songs. In addition, the users can conduct instant communications and play online games via network platforms provided by the network operators.

These third-party applications are usually associated with certain servers (e.g., third-party servers) and account systems. That is, a user who intends to access a third-party application needs to log into a network platform using an instant messaging account and a password. Then, the user inputs the account and the password for the third-party application on an interface of the third-party application shown on the network platform. The user account and the password are sent to a third-party server via the network platform. After the third-party server validates the user account and the password, the user can successfully log into the third-party application. Thus, every time the user accesses a third-party application, the user needs to input a user account and a password and/or even a validation code. Account systems of many third-party applications require the user to set a complicated password to ensure sufficient password strength. Therefore, it is not easy for users to remember accounts and associated passwords. Often, a user may forget the accounts and associated passwords. In particular, for mobile equipment (e.g., tablet computers) that has no external keyboard, it is usually inconvenient for users to input accounts, passwords and/or other information.

Furthermore, plaintext passwords transmitted on the Internet for third-party application logins may be intercepted by hackers, which results in leakage of user account data and privacy data. Usually, a user may use multiple third-party applications and a same password may be implemented for these third-party applications. If the leakage of an account and an associated password for a particular third-party application may cause security issues to a plurality of third-party applications.

Hence it is highly desirable to improve the techniques for login and authorization.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a simplified diagram showing a method for login and authorization according to one embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. The method 100 includes at least the processes S101-S112.

According to one embodiment, during the process S101, the third-party terminal receives a login request from a user. For example, the third-party terminal can display to the user a login interface of a third-party application. In another example, during the process S102, the third-party terminal sends an authorization request to the network server after receiving the login request. The authorization request may include one or more authorization parameters such as an application identifier (e.g., “appid”), authorization scope information (e.g., “scope”), an application callback address (e.g., “redirect_url”), anti-disguise information (e.g., “state”) and/or an application key (e.g., “appkey”). In yet another example, the application identifier “appid” represents an application identifier number allocated by a network server to the third-party application. In yet another example, a particular application identifier “appid” corresponds to a particular third-party application. In yet another example, the authorization scope information “scope” refers to an authorization scope of operations associated with a user account after the third-party server receives authorization from the network server. As an example, the third-party application is authorized to use a headshot and/or a nickname associated with the user account, or authorized to post a microblog message on behalf of the user. As another example, the application callback address “redirect_url” represents an address at which the third-party application receives information. As yet another example, the anti-disguise information “state” and application key “appkey” are used to improve the security of data transmission.

According to another embodiment, during the process S103, the network server generates two-dimensional-barcode information after receiving the authorization request. For example, a two-dimensional barcode, or a matrix barcode, represents a readable barcode developed based on one-dimensional barcodes. In another example, a device scans a two-dimensional barcode to identify binary data recorded along the length and the width of the barcode and hence acquire two-dimensional-barcode information contained therein. Compared with a one-dimensional barcode, a two-dimensional barcode records more complicated data, such as images and network links. In another example, the two-dimensional-barcode information includes the authorization parameters, e.g., the application identifier (e.g., “appid”), the authorization scope information (e.g., “scope”), the application callback address (e.g., “redirect_url”), the anti-disguise information (e.g., “state”) and/or the application key (e.g., “appkey”).

According to yet another embodiment, during the process S104, the network server sends the two-dimensional-barcode information to the third-party terminal. For example, during the process S105, the third-party terminal displays a two-dimensional-barcode image after receiving the two-dimensional-barcode information. In another example, during the process S106, the mobile terminal extracts the two-dimensional-barcode information in the two-dimensional-barcode image. As an example, scanning software installed on the mobile terminal is used to scan the two-dimensional-barcode image to extract the two-dimensional-barcode information therein. In yet another example, during the process S107, the mobile terminal sends user account information and the information extracted from the two-dimensional-barcode image to the network server.

In one embodiment, during the process S108, the network server validates the user account information and the two-dimensional-barcode information sent from the mobile terminal according to stored user account information and other two-dimensional-barcode information generated by the network server. For example, an application for scanning two-dimensional barcodes is started on the mobile terminal to send the user account information. In another example, the application and the network server are from a same network operator. The application can be logged in. The user account information is transmitted to the network server and the validation process is completed during the login process of the application. As an example, the user account information can be validated so long as a user pre-stores (e.g., registers) an account in the network server in advance. In one example, after validation, a communication link between the mobile terminal and the network server is established so that the two-dimensional-barcode information can be sent to the network server for validation.

In another embodiment, during the process S109, if the validation is successful, the network server sends authorization information (e.g., an authorization) and a predetermined user identifier to the third-party server. For example, the user identifier represents a unique identifier of a user after the user logs into a third-party application. As an example, based on the user identifier, the third-party application allows the login of the corresponding user. In one example, a user identifier uniquely corresponds to a user account. In another example, when a user account logs into different third-party applications, the user account corresponds to different user identifiers. For example, the authorization information includes an authorization validity character string (e.g., “token”) and anti-disguise information (e.g., “state”). The authorization validity character string (e.g., “token”) is configured to indicate the validity of the user authorization, and the anti-disguise information (e.g., “state”) works to improve the security of data transmission, in some embodiments.

In yet another embodiment, during the process S110, the third-party server sets a user account corresponding to the received user identifier to a logged-in state. For example, during the process S111, the third-party terminal acquires information related to the logged-in state from the third-party server. In another example, during the process S112, the third-party terminal sets an interface of the third-party application to a user-logged-in state.

FIG. 2 is a simplified diagram showing a method for login and authorization according to another embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. The method 200 includes at least the processes S201-S219.

According to one embodiment, during the process S201, the third-party terminal receives a login request from a user. For example, during the process S202, the third-party terminal sends an authorization request to the network server after receiving the login request. In another example, the authorization request may include one or more authorization parameters such as an application identifier (e.g., “appid”), authorization scope information (e.g., “scope”), an application callback address (e.g., “redirect_url”), anti-disguise information (e.g., “state”) and/or an application key (e.g., “appkey”). In yet another example, during the process S203, the network server validates the authorization parameters in the authorization request. For instance, the validation process includes determining if the application identifier “appid”, the authorization scope information “scope” and the application callback address “redirect_url” are consistent with the predetermined parameters that are assigned to the third-party application.

According to another embodiment, during the process S204, the network server generates two-dimensional-barcode information after receiving the authorization request. For example, the two-dimensional-barcode information includes the authorization parameters, e.g., the application identifier (e.g., “appid”), the authorization scope information (e.g., “scope”), the application callback address (e.g., “redirect_url”), the anti-disguise information (e.g., “state”) and/or the application key (e.g., “appkey”). In another example, during the process S205, the network server sends the two-dimensional-barcode information to the third-party terminal. In yet another example, during the process S206, the third-party terminal displays a two-dimensional-barcode image after receiving the two-dimensional-barcode information.

According to yet another embodiment, during the process S207, the third-party terminal sends one or more authorization inquiries at one or more predetermined times to the third-party server. For example, the authorization inquiries are used to inquire about the login state of the user. That is, whether the third-party server receives the user identifier, so that the login state displayed on the third-party application can be updated in a timely manner after the authorization is passed. In another example, during the process S208, the mobile terminal extracts information from the two-dimensional-barcode image. As an example, scanning software installed on the mobile terminal is used to scan the two-dimensional-barcode image to extract the two-dimensional-barcode information therein.

In one embodiment, during the process S209, the mobile terminal sends user account information and the information extracted from the two-dimensional-barcode image to the network server. For example, during the process S210, the network server validates the user account information and the two-dimensional-barcode information sent from the mobile terminal according to stored user account information and other two-dimensional-barcode information generated by the network server. In another example, during the process S211, if the validation is successful, the network server sends the validation-success information to the mobile terminal. In yet another example, during the process S212, the mobile terminal displays authorization confirmation information. In yet another example, the authorization confirmation information includes a name of a third-party application and an authorization scope of the third-party application, so that a user knows the name and the authorization scope of a target application.

In another embodiment, during the process S213, the mobile terminal receives an authorization confirmation from a user. For example, the user is given a chance to choose whether to log into the third-party application via a user account. In another example, during the process S214, the mobile terminal sends the authorization confirmation from the user to the network server. In yet another example, during the process S215, the network server sends authorization information (e.g., an authorization) and a predetermined user identifier to the third-party server. For example, the user identifier represents a unique identifier of a user after the user logs into a third-party application. As an example, based on the user identifier, the third-party application allows the login of the corresponding user. In one example, a user identifier uniquely corresponds to a user account. In another example, when a user account logs into different third-party applications, the user account corresponds to different user identifiers. For example, the authorization information includes an authorization validity character string (e.g., “token”) and anti-disguise information (e.g., “state”).

In yet another embodiment, during the process S216, the third-party server validates the received authorization. For instance, the validation process includes determining if the anti-disguise information “state” is in the authorization information. As an example, during the process S217, the third-party server sets a user account corresponding to the received user identifier to a logged-in state. As another example, during the process S218, the third-party terminal acquires information related to the logged-in state from the third-party server. In one example, during the process S219, the third-party terminal sets an interface of the third-party application to a user-logged-in state.

FIG. 3 is a simplified diagram showing a method for login according to one embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. The method 300 includes at least processes S301-S306.

According to one embodiment, the process S301 includes receiving a login request from a user. For example, the process S302 includes sending an authorization request to a network server. The authorization request may include one or more authorization parameters such as an application identifier (e.g., “appid”), authorization scope information (e.g., “scope”), an application callback address (e.g., “redirect_url”), anti-disguise information (e.g., “state”) and/or an application key (e.g., “appkey”). In another example, the process S303 includes receiving two-dimensional-barcode information sent from the network server. In yet another example, the two-dimensional-barcode information includes the authorization parameters, e.g., the application identifier (e.g., “appid”), the authorization scope information (e.g., “scope”), the application callback address (e.g., “redirect_url”), the anti-disguise information (e.g., “state”) and/or the application key (e.g., “appkey”).

According to another embodiment, the process S304 includes displaying a two-dimensional-barcode image. For example, the process S305 includes acquiring information related to a logged-in state of a user account from a third-party server. In another example, the information related to the logged-in state of the user account is sent after the network server validates the user account information sent from a mobile terminal and the information extracted from the two-dimensional-barcode image and the third-party server sets the user account to the logged-in state. In yet another example, the process S306 includes setting an interface of a third-party application to a user-logged-in state.

FIG. 4 is a simplified diagram showing a method for login according to another embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. The method 400 includes at least processes S401-S407.

According to one embodiment, the process S401 includes receiving a login request from a user. For example, the process S402 includes sending an authorization request to a network server. The authorization request may include one or more authorization parameters such as an application identifier (e.g., “appid”), authorization scope information (e.g., “scope”), an application callback address (e.g., “redirect_url”), anti-disguise information (e.g., “state”) and/or an application key (e.g., “appkey”). In another example, the process S403 includes receiving two-dimensional-barcode information sent from the network server. In yet another example, the two-dimensional-barcode information includes the authorization parameters, e.g., the application identifier (e.g., “appid”), the authorization scope information (e.g., “scope”), the application callback address (e.g., “redirect_url”), the anti-disguise information (e.g., “state”) and/or the application key (e.g., “appkey”).

According to another embodiment, the process S404 includes displaying a two-dimensional-barcode image. For example, the process S405 includes sending one or more authorization inquiries at one or more predetermined times to a third-party server. In another example, the authorization inquiry information is used to inquire about the login state of the user, namely whether the third-party server receives the user identifier, so that the login state displayed on the third-party application can be updated in a timely manner after the authorization is passed. In yet another example, the process S406 includes acquiring logged-in state information of a user account from the third-party server. The user account logged-in state information is sent after validation of the network server on the user account information sent from a mobile terminal and the information read from the two-dimensional-barcode image is passed and the third-party server sets the user account to the logged-in state. In yet another example, the process S407 includes setting an interface of a third-party application to a user-logged-in state.

FIG. 5 is a simplified diagram showing a method for authorization according to one embodiment of the present invention.

According to another embodiment, the process S503 includes sending the two-dimensional-barcode information to the third-party terminal so that the third-party terminal displays a two-dimensional-barcode image. For example, the process S504 includes receiving user account information and the two-dimensional-barcode information sent from the mobile terminal, where the two-dimensional-barcode information sent from the mobile terminal is acquired by the mobile terminal from the two-dimensional-barcode image displayed on the third-party terminal. In another example, the process S505 includes validating the user account information and the two-dimensional-barcode information sent from the mobile terminal according to stored user account information and other two-dimensional-barcode information generated by the network server.

According to yet another embodiment, the process S506 includes, if the validation is successful, sending authorization information (e.g., an authorization) and a predetermined user identifier to the third-party server. For example, the user identifier represents a unique identifier of a user after the user logs into a third-party application. As an example, based on the user identifier, the third-party application allows the login of the corresponding user. In one example, a user identifier uniquely corresponds to a user account. In another example, when a user account logs into different third-party applications, the user account corresponds to different user identifiers. For example, the authorization information includes an authorization validity character string (e.g., “token”) and anti-disguise information (e.g., “state”).

For example, the process S607 includes, if the validation is successful, sending validation-success information to the mobile terminal. In yet another example, the authorization confirmation information includes a name of a third-party application and an authorization scope of the third-party application, so that a user knows the name and the authorization scope of a target application. In yet another example, the process S608 includes receiving an authorization confirmation from the user sent from the mobile terminal, which indicates that the user confirms to log into the third-party application. In yet another example, the process S609 includes sending authorization information (e.g., an authorization) and a predetermined user identifier to the third-party server. For example, the user identifier represents a unique identifier of a user after the user logs into a third-party application. As an example, based on the user identifier, the third-party application allows the login of the corresponding user. In one example, a user identifier uniquely corresponds to a user account. In another example, when a user account logs into different third-party applications, the user account corresponds to different user identifiers. For example, the authorization information includes an authorization validity character string (e.g., “token”) and anti-disguise information (e.g., “state”).

FIG. 7 is a simplified diagram showing a login-and-authorization system according to one embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. The login-and-authorization system includes one or more mobile terminals 701, one or more third-party terminals 702, a network server 703 and a third-party server 704.

According to one embodiment, the mobile terminals 701, the third-party terminals 702, the network server 703 and the third-party server 704 are connected to a network 705. For example, one or more users 706 operate the mobile terminals 701 and the third-party terminals 702. In another example, when the users 706 input a login request on an interface of a third-party application displayed on the third-party terminals 702, the interface of the third-party application displays a user login prompt. In yet another example, the third-party terminals 702 send an authorization request to the network server 703. In yet another example, the network server 703 generates two-dimensional-barcode information and sends the two-dimensional-barcode information to the third-party terminals 702 after receiving the authorization request sent from the third-party terminals 702. In yet another example, the third-party terminals 702 displays a two-dimensional-barcode image after receiving the two-dimensional-barcode information sent from the network server 703.

According to another embodiment, when the users 706 view the two-dimensional-barcode image displayed on the interface of the third-party terminals 702, the users 706 use a scanning tool on the mobile terminals 701 to scan the two-dimensional-barcode image and extract the information contained therein, and then sends user account information and the information extracted from the two-dimensional-barcode image to the network server 703 through the mobile terminals 701. For example, after receiving the user account information and the two-dimensional-barcode information extracted from the image sent from the mobile terminals 701, the network server 703 validates the user account information and the two-dimensional-barcode information sent from the mobile terminals 701 according to stored user account information and other two-dimensional-barcode information generated by the network server. In yet another example, the scanning tool on the mobile terminals 701 includes an application for scanning and login that is supplied by an operator of the network server 703, such as an instant messaging software. In yet another example, when the users 706 logs into the application in the mobile terminals 701 using a user account, the validation of such user account by the network server 703 is completed. The information acquired by the mobile terminals 701 through scanning the two-dimensional-barcode image is sent to the network server 703 for validation, in some embodiments.

According to yet another embodiment, if the validation is successful, the network server 703 sends authorization information (e.g., an authorization) and a predetermined user identifier to the third-party server 704. For example, the user identifier represents a unique identifier of the users 706 after the users 706 log into the third-party application. As an example, based on the user identifier, the third-party application allows login of the corresponding users 706, and the authorization process is completed. In one example, the third-party server 704 sets the user account corresponding to the user identifier to a logged-in state after receiving the authorization information and the predetermined user identifier sent from the network server 703. In another example, after acquiring information related to the logged-in state of the user account from the third-party server 704, the third-party terminals 702 set the interface of the third-party application to a user-logged-in state, and the login process is completed.

In one embodiment, the authorization request sent by the third-party terminals 702 to the network server 703 includes authorization parameters, e.g., the application identifier (e.g., “appid”), the authorization scope information (e.g., “scope”), the application callback address (e.g., “redirect_url”), the anti-disguise information (e.g., “state”) and/or the application key (e.g., “appkey”). For example, the network server 703 validates the authorization parameters in the authorization request after receiving the authorization request sent from the third-party terminals 702. For instance, the validation process includes determining if the application identifier “appid”, the authorization scope information “scope” and the application callback address “redirect_url” are consistent with the predetermined parameters that are assigned to the third-party application. In one example, the two-dimensional-barcode information generated by the network server 703 includes the authorization parameters. In another example, the third-party terminals 702 regularly send authorization inquiries to the third-party server 704 after displaying the two-dimensional-barcode image. For example, the authorization inquiries are used to inquire about the login state of the users 706. In another example, the authorization inquiries are used to inquire about whether the third-party server 704 receives the user identifier, so that the login state displayed on the third-party application can be updated in a timely manner after the authorization is passed.

In another embodiment, after the validation of the user account information and the two-dimensional-barcode information sent from the mobile terminals 701 is passed, the network server 703 sends the validation-success information to the mobile terminals 701 so that the mobile terminals 701 displays the authorization confirmation information. The authorization confirmation information includes a name of a third-party application and an authorization scope of the third-party application, so that a user knows the name and the authorization scope of a target application. For example, the users 706 can be given a chance to choose whether to log into the third-party application via a user account. In another example, the mobile terminals 701 receive the authorization confirmation from the users 706 and send the authorization confirmation to the network server 703 so that the network server 703 sends authorization information (e.g., an authorization) and a predetermined user identifier to the third-party server 702. For example, the user identifier sent by the network server 703 to the third-party server 704 uniquely corresponds to a user account. In another example, when a user account logs into different third-party applications, the user account corresponds to different user identifiers. For example, the authorization information sent by the network server 703 to the third-party server 704 includes an authorization validity character string (e.g., “token”) and anti-disguise information (e.g., “state”). In another example, the third-party server 704 validates the authorization information after receiving the authorization information sent from the network server 703. For instance, the validation process includes determining whether the anti-disguise information “state” is in the authorization information.
